'Sherlock' trailer: Tension between friends

A new trailer for "Sherlock" Season 3 offers more than a flash of the detective.

An earlier trailer showed fans Benedict Cumberbatch's character was alive after faking his death in the Season 2 finale. Now we see that upon his return to the land of the living, neither his razor sharp wit nor his belief in his own superiority have been dulled.

Sherlock also talks to someone about the "one person he thought didn't matter to me," and Mycroft informs his brother that "the terrorist alert has been raised to critical" and "an attack is coming," so it looks like there will be plenty of intrigue in the new season.

"Sherlock," which Gatiss and Steven Moffat based on the Sir Arthur Conan Doyle stories, returns Jan. 19 to PBS with the Season 3 premiere, "The Empty Hearse." "The Sign of Three" follows on Jan. 26 and "His Last Vow" airs Feb. 2.
